These eye drops are like an extremely powerful rollercoaster-like mouthwash for your eyes. As soon as the drops make contact with your eye, your eyelids will immediately squeeze shut as you feel a rushed stinging sensation. Your eyes will start to water uncontrollably as the slight burning sensation begins to fade, you feel overcome with a pleasant, cool sensation that is revitalizing and reminiscent of the wind hitting your eyes on a cold winter day. After 30 seconds have passed, this product will leave you feeling like you literally took your irritated, itchy, dry eyes out and put in a brand new pair that suddenly feel a million times better. Every time you use this product you'll go through this rollercoaster of burning-to-pleasant sensation that I would highly suggest to anyone sick of the same-old boring eye drops!
